Calcium, Chemical Element - structure, reaction, …

Chemical properties Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogens— fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table. Calcium also reacts readily with cold water, most acids, and most nonmetals, such as sulfur and phosphorus.

Calcium Element Facts

Calcium is reactive and, for a metal, soft. With a bit of effort, it can be cut with a sharp knife. In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal burns brightly in air, forming mainly the nitride. Uses of Calcium
